TRILLIUM 120P SEISMOMETER


1 16 Jan 2008: Test of cable pin-out.


Seismometer:

Instrument connector is a 19-pin male military circular type.

The instrument User Manual does not contain a connector pin-out drawing. To check pin-out we need manufacturer's datasheet.

Mating connector:

  • Mfr: Souriau, http://www.souriau.com
  • Mod: MS3475L 14-19S
  • Connector "family": MIL-C 26482G Series II
  • Datasheet: mil-c-26482sII.pdf. Connector pin-out is on page 4 of this datasheet, shell size/pattern: 14-19. The drawing is of very low quality, so the figure below is from Amphenol datasheet of similar connector.

1.1 Pin-out of instrument connector.

Cable connector is of socket type, so all pin positions on cable connector must be mirrored.

Pin-out, instrument connector, size 14 pin no.: 19. Cable connector is mirrored. From Amphenol datasheet: Amphenol-ELFA-04453528.pdf
